I find interesting and intriguing the discussion: understand how 
things works is of course very important and leave to other to state if 
this has to come before or after experimentation.
My first approach to MW was dictated from hirony.. how can such thing 
work? After almost 2 years of use I still have doubts of interactions 
between all the wire on my roof and the MW itself but finally is a gear 
that makes some work. Under some circumstance better than standard wire 
antennas, in other cases worse but today almost all my LF/MF receptions 
are made with a MW.
The idea that the E probe is similar to a cap plate against the 
universe can explain some aspects if not all.
What about the same idea applied to a TX antenna? (antennas should be 
reversible items..)

I don't know if my previous posts arrived but I still prefer to think 
that a "small" antenna is one plate of a capacitor and the rest of the 
universe is the other. This then enables the spacecraft antenna to 
work. 
The universe is not a great big empty space!
